A Damsel For The Mysterious Duke by Bridget Barton
This is a captivating, suspenseful and romantic story. Sammy is unsure, sweet, charming and engaging. Georgina is determined, loyal and kind. When Sammy sees Georgina for the first time in years, he's very happy, but also afraid that if she finds out that he is the former servant and friend from childhood, she could ruin his life. But she's just happy to find him again. Their friendship becomes a search for his past that is twisted and filled with tragedy. I couldn't put the book down trying to figure out who he really was. It's a brilliant and intriguing, and the characters vary from very sweet and charming, to evil. I highly recommend adding it your TBR list.
